Groundwater Remediation Webinar Will Highlight Field Study Results on
PersulfOx™, a New Catalyzed Persulfate Technology from REGENESIS

February 14, 2013 10:00 AM Eastern Daylight Time

SAN CLEMENTE, Calif.--(BUSINESS WIRE)--REGENESIS, a leader in the development of advanced environmental
remediation technologies, will host a free online technical presentation
(webinar) titled “Remediation Field Studies Evaluating the Effectiveness
of Catalyzed Persulfate (PersulfOx™) vs. Base-Activated Persulfate” on
Thursday, February 21, 2013, from 11:00 AM to noon Pacific Standard
Time. The webinar will focus on two groundwater remediation field study
sites where both PersulfOx and conventional base-activated persulfate
were applied to treat petroleum hydrocarbons. The online presentation
will be hosted by REGENESIS and given by Rick McGregor, President of
InSitu Remediation Services Ltd., who performed the actual remediation
at both field sites. Rick, a hydrogeologist and geochemist by training,
is widely recognized as an expert in his field. Collectively he has
worked in the groundwater and soil remediation industry for over 20
years in both research and field application.

The webinar presentation will feature information on two remediation
projects, one with heating oil in fractured bedrock and one with
gasoline in a shallow, unconfined, silty sand aquifer. The studies were
designed to evaluate the performance of conventional base-activated
persulfate vs. the PersulfOx reagent with respect to treatment results
as well as material delivery, subsurface distribution, and other
significant parameters. PersulfOx is a safe, easy-to-handle in situ chemical
oxidation (ISCO) reagent that destroys common groundwater contaminants
on contact. PersulfOx is unique in that it was engineered with a
built-in catalyst that eliminates complex and potentially hazardous
chemical activation used in traditional persulfate application. To learn
